1) You're right about there being a COC requirement to be provided by the seller in deeds of sale (contract).
We're not sure if after major changes have been done to the wirings, it's still fair or doable for the seller to conduct a COC.
2)There's no occupational rent; he is the new owner after the transfer.
It's like the seller didn't receive the full purchasing money on the day of transfer, and the title deed is kept by the attorney firm.
At the time, the buyer had up to 90% of the purchasing price in his bank account.
So, for the remaining 10% of the purchasing price, he did a private mortgage bond registered against the title deed.
We feel it's like a bank mortgage loan, except in our case it's the seller offering the loan in place of a bank, and an attorney firm acts like a keeper to hold the buyer's title deeds for the interest of the seller until all the bond payments are paid off.(remaining 10% purchasing price paid to seller)
3)there's no real estate agent involved, the buyer came to ask the seller if he is interested in selling his property.
